The Effects Of Non-Plastic and Plastic Fines On The Liquefaction Of Sandy Soils
… conclusions can be drawn as to how altering fines content and plasticity actually affects the liquefaction resistance of a sand. In fact, the literature contains what appears to be contradictory evidence. There is a need to clarify the effects of fines content and plasticity on the …

Effects Of The Soil Properties On The Maximum Dry Density Obtained Fro
… many factors, the most common are the moisture content, the soil type and the applied compaction energy. The objective of this research is the analysis of the maximum dry density values based on the soil classification and characterization. The method of choice in the determination of the …

Role of cement content in determining resistance of concrete to reinforcement corrosion
… performance in some cases. However, cement content variations (in some cases) are relatively small and do not cover an adequate range around the specified minimum cement contents in standards. In addition, insufficient data exist to establish relationships between cement content and …

Performance of Silty Sands and their Use in Flexible Airfield Pavement Design
… with actual practice where a wide range of fines and soil gradations could be present in a real-world project. This research investigates the characteristics of natural sands and examines the influence of these marginal materials in pavement design using element testing and controlled …

Use of Cone Penetration Testing in the Interpretation of Ground Shaking From Paleoliquefaction Evidence
… of criteria that allow the effect of measured fines content on liquefaction resistance to be quantified. This refined database allows for the development of liquefaction resistance relationships based on the magnitude of the earthquake-induced shear stress and on the energy dissipated in the …

Fluidized-Bed combustion of coal
… from the combustion of a coal with a high fines content of which there is at present a supply which exceeds the demand. The coal has been burned in an inert bed comprising a closely graded silica sand. It has been found possible to correlate the combustion efficiencies in terms of the bed …

Development of an Improved and Internally-Consistent Framework for Evaluating Liquefaction Damage Potential
… damage potential at sites having high fines-content, high plasticity soils; (3) development of a new manifestation model, termed Ishihara-inspired Liquefaction Severity Number (LSNish), that more fully accounts for the effects of non-liquefiable crust thickness and the effects of …

Sustainable advancements in rural infrastructure: Enhancing gravel road performance, stabilization, and intelligent monitoring
… vehicle speed (25–50 mph) and surface fines content with emissions using field-collected data from Iowa gravel roads. The model provides actionable thresholds for dust suppression, enabling agencies to implement targeted speed controls and material treatments. While accurate for typical …

The use of Lethabo field 2 PFA in pavement quality concrete
… The dune sand typically has very little fines content, causing severe bleeding problems in normal concrete mixes. The crushed coarse aggregate was 13 mm and flaky in shape. Ordinary Portland cement (OPC) was obtained from the De Hoek cement factory. The investigation was carried out in …

Geotechnical Investigation of Uranium Tailings
… of borehole data indicated that the high water content (100% to 250%) at the tailings surface gradually decreased with depth and reached around 60% to 80% at the DTMF bottom. The corresponding solids content values were found to be 30 ± 5% at the surface and 60 ± 5% at the bottom. The grain size …

Case history-based analysis of liquefaction in sloping ground
… contractive-dilative boundaries; (2) the role of fines content on liquefaction susceptibility in sloping ground conditions; and (3) the viability of an extended cone penetration test “compressibility” correction factor for susceptibility analysis. If a soil deposit is susceptible to liquefaction, …

Modelling fine sediment transport over an immobile gravel bed
… by a number of observations, because the fines content of the bed fs may often be more variable than that of the coarse fraction (i.e. partial mobility condition), and whose passage, intrusion, or removal may be a specific environmental or engineering objective. The problem of sand …
